I wouldn't mind more options, but I'm already scared just thinking about certain champs if a stun were to be added to their arsenal... Also, as mentioned above, this would completely destroy channeling ults, making them basically impossible to use. Some other options would be nice, though

I was thinking, since we have Flash and Ghost, which are basically two ways to either initiate or disengage, we could also grab more options for Heal . We could have something like, instead of an instant AoE heal, a Regeneration spell that dramatically increases HP regen for 10 seconds or so. This would be a nice option for Tanks, it would be useless for Mages or Assasins since most of them die in a heartbeat if focused, but it would be actually pretty awesome for tanky champs. I don't even play tanks, but I doubt this would be OP, considering it could be easily countered by Ignite and the utility is there... I can totally see tanks backdooring using this spell to counter turret damage and destroy them without minion waves.

Another option would be a summoner spell that would increase the target's cooldowns by a large amount, but only for a few seconds. It would be an interesting option to get instead of Exhaust, you'd use this on AP carries with a lot of CDR.

They just need to improve the other spells to make them more viable. When was the last time you saw someone running clairvoyance? Clarity? Revive?

Actually I at time use Clarity and Clairvoyance on Janna and then use Eleisa's Miracle but that really depends on the situation honestly and I only do it some times.

But yea we could use another Summoner Spell or have the other ones improved, it's a little tiring to see the same summoner spells (Flash, Exhaust, Ignite and some times Ghost) I think the other summoner spells needs to be improved.
